Amplitude relations for $B$ decays involving $\eta$ and ${\eta }^{\prime }$

Abstract

A class of amplitude relations for decays of $B$ mesons is discussed. Processes involving $\eta$ and ${\eta }^{\prime }$ in the final state are shown to provide useful information about weak phases in some cases even in the presence of octet-singlet mixing in these states. Some of the relations are unaffected by first-order SU(3) breaking.
